rotisserie problem

Mine has long bottle style jacks built in.
I had to bring the body up about 12” to start the process.
I made it easy and put the car on my 2 post lift and raised it to put it on and off the rig. Once on the rig I lowered the lift.
I realize that is not the case for everyone. Having a lift is a true blessing. Especially the older you get. If you use a floor jack and cinder blocks you can raise the body (or even jack stands I guess) to get it up over the cross support down the middle.
